Specification of Letters Patent.

Patented May 11, 1915.

Application filed January 9, 1909. Serial No. 471,388.

To all whom it may concern.

Be it known that I, EDWIN WALKER, a citizen of the United States, residing in Erie, in the county of Erie and State of Pennsylvania, have invented a certain new and useful Ice-Cream Dipper, of which the following is a specification.

This invention is an ice cream dipper of simple construction and economical to manufacture, yet so organized that the parts thereof may be quickly assembled, and, also,

quickly dismantled by the user for the purpose of thoroughly cleaning the same. Sanitary authorities h ve called attention to the fact that considerable danger resides in dispensing cream from insanitary dippers, 2'. e., dippers which permit the lodgment of cream in or around such operating parts of the device as cannot be thoroughly cleansed or sterilized, at least without much greater care than is ordinarily bestowed in cleansing utensils of this character.

The salient features of novelty in the present invention reside in a particular construction of the scraper, means for securing close contact between the inner wall of the cup and the scraper, and means for locking the scraper in its operative position whereby it may be readily removed.

In the accompanying drawings, I have illustrated practical embodiments of the invention, but the constructions shown therein are to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1. is a side elevation partly in section of an ice cream dipper embodying the invention. Fig. 2 is a vertical section on line 2 2 of Fig. 1, the rotary scraper being shown in elevation. Fig. 3 is an inverted or bottom pl an view of the scraper and the cup, a part of the handle being shown. Fig. 4: is a plan view showing a preferred form of construction of the detachable member. Figs. 5, 6, 7, 8 and 9 are views illustrating another embodiment of the invention.

The dipper shown in Figs. 1 to 4 of the drawin embodies in its construction a cup,

A, and a handle, B, the latter being received in a socket portion, a, which is integral with cup, A As shown, the cup is substantially conical, although its particular form is not a material feature. Furthermore, handle, B, is composed of wood, or other non-metallic substance, and it is secured rigidly in a socket portion, a, but it is evident that these details of construction may be varied by a skilled constructor. Cup, A, is normally open at the base thereof, the opening being indicated at c in Fig. 2, and through this opening extends a part of a rotatable scraper,

In one embodiment of the invention the scraper consists of a strip or plate which is stamped, out, or otherwise produced from sheet metal. Said metal is doubled or bent upon itself to produce the diverging members or legs, 0, c and loop 0 D designates a member positioned intermediate the diverging legs of the scraper. As shown, member, D, is in the form of a plate which bridges the space between said legs below or adjacent to loop, 0 The member or plate is secured rigidly to the legs, and in the construction shown, said member performs two important functions; first, the member precludes cream from passing through bottom opening, 0, of cup, A, thereby serving as a closure for the cup, and, second, the member tends to spread legs, 0, 0 which are yieldable somewhat when the scraper is introduced into the cup, whereby the legs are caused to lie in close frictional contact with the inner surface of the cup.

The scraper is removable easily and quickly from cup, A, in orderthat the inner surface of said cup, as well as the scraper, may be thoroughly cleaned'orsterilized, but it is preferred to provide means which serves the twofold purpose of locking the scraper in its operative position within the cup and for rotating said scraper while retained in said position. The means shown for securing these results is a detachable member or key, E, adapted to be inserted into the looped part, 0 of the scraper, and to engage with the edge of the cup at the open end, 0, thereof. Said detachable member is shown as being composed of wire, or other appropriate material, which is bent to produce a loop, 6, arms, 6', and fingers, e 6 all of the parts being in the same plane. The fingers extend inwardly with respect to the arms and the loop, said fingers being intermediate said arms. The member or key is yieldable somewhat when its arms, 6, are brought into engagement with the closed end of the loop, 0 and open end, 0, of cup, A, whereby member or key is adapted to retain itself in position within the looped part of scraper C. For the purpose of precluding accidental separation of the member or .key from scraper, C, it is preferred to bend the fingers, c 6 in opposite directions to each other, as shown in Fig. 4. Thus, the finger, 6 is bent outwardly in one direction as at 7, whereas the finger, 6 is bent outwardly in an opposite direction as at f, whereby said bent parts, 7, f, of the respective fingers are adapted for engagement frictionally with opposite sides or walls of loop, 0 thus retaining a member or key, E, firmly in position within the looped part of the scraper.

By reference to Fig. 1 of the drawings it will be noted that the key or member is exposed on or extends beyond the respective sides of the looped part of the scraper, and these exposed parts of the key are adapted to be grasped by the fingers of the operators hand, whereby the member, is adapted to serve as a handle in rotating the scraper within the cup. Said member engages with the closed end of loop, 0 and with the edge of cup, A, at the open end thereof, the result of which is that said member or key retains the scraper in its operative position within the cup.

When using the device, the operator thrusts cup, A, into the cream or water-ice until said cup is filled with the substance, and the implement is then withdrawn and held over a dish, saucer or other receptacle, whereupon the operator rotates member or key, E, and the scraper is rotated within cup, A. The legs, 0', c of the scraper are in close contact with the inner surface of the cup, and upon rotary motion being given to the scraper, said legs cut the cream or ice from the cup, whereby the product may be discharged from the dipper.

Should it be desired to clean the dipper, the operator first withdraws member or key, E, from the loop, 0 the fingers, e 6 yielding to the pull of the key, and thereafter the scraper may be removed from the cup, loop, 0 of said scraper passing easily through open end, 0, of the cup. The scraper and the cup may now be thoroughly washed for the purpose of removing any cream which adheres to the surfaces thereof. In replacing the scraper, it is introduced into the large end of the cup and loop, 0 passes through opening, a, the scraper assuming the position shown in dotted lines shown in Fig. 2. The scraper can be fully drawn into the cup by pulling the loop, 0 so that the scraper will assume the full line position of Figs. 1 and 2, and thereafter key or member, E, is inserted into the loop of said scraper, one arm of the key engaging with the small end of the cup while the other arm of said key engages the closed end of the loop. The bent ends, 7, f, of the fingers engage with the respective edges of the loop so as to effectually retain said key in position.

The dipper shown in Figs. 1, 2 and 3 comprises a cup having a socket integral therewith, the whole being preferably cast in any suitable metal, but in Figs. 5 to 9 inclusive, there is shown another embodiment of the invention wherein the cup is composed of sheet metal and the handle is made by bending wire, it being preferred to employ the material known as cotter wire which is characterized by flat and rounded faces as shown in Fig. 8. The cup, A, of Fig. 5 is stamped or cut from sheet metal with a seriesof tongues, g, g, on the end edges of the blank. Said blank is adapted to be formed into the shape required for the cup, and when the edges are brought together, the tongues thereon interlock as shown in Fig. 5, said tongues being preferably dovetailed to secure the interlocking engagement between said edges. The handle, B, is formed by bending suitable wire into a loop, H, said wire being twisted one or more times together as at h, the flat faces of said wire being in contact, whereby the handle is provided with a shank, 71.. The end portions of the wire are bent in opposite directions and to assume the inclined positions shown in Figs. 6 and 9, thus producing base, I, at one end of the handle, said base being at an angle to the longitudinal axis of said handle. The flat face of the base is applied to the cup in a position to cover the interlocked tongues g, g, thereof, and the handle and cup are united in a suitable way, as for example, by riveting the parts together although it is preferred to solder them as shown in Fig. 9.

Instead of using a handle composed of wire in the manner described, said handle may be of cast metal, but it should be provided with a base, the angle of inclination of which conforms to the angle of the cup.

The dipper constructed as shown in F igs. 5 to 9, inclusive, should be provided with a scraper and the detachable locking member or key, as in the construction of Fig. 1 to 3, inclusive. Said sheet metal and wire dipper of Figs. 5 to 9 may be manufactured economically, for the reason that the parts may be cut and bent by appropriate machinery and quickly assembled.

It is found that the wings or blades of the scraper have a tendency, at times, to be forced inwardly toward each other by the pressure or resistance of the cream,- so that under some circumstances the scraper wings or blades become bent or distorted out of position, thus precluding the scraper from sweeping close to, or in contact with, the walls of the cup or receptacle. My invention enables the scraper to be detached easily from the cup or receptacle, and the blades thereof can be restored to their normal positions. For example, the w1ngs can be bent back into shape or position, or the bridge piece can be replaced by another which will operate to hold the wings in position, or other changes in the device may be made with the end in view of making the wings retain their proper working posltlons. Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is:
